This method asynchronously loads the URL. When the operation starts, the Media Engine sends an MF_MEDIA_ENGINE_EVENT_LOADSTART event. If no errors occur during the Load operation, several other events are generated, including the following.

MF_MEDIA_ENGINE_EVENT_LOADEDMETADATA

MF_MEDIA_ENGINE_EVENT_LOADEDDATA

MF_MEDIA_ENGINE_EVENT_CANPLAY

MF_MEDIA_ENGINE_EVENT_CANPLAYTHROUGH

If the Media Engine is unable to load the URL, the Media Engine sends an MF_MEDIA_ENGINE_EVENT_ERROR event.
